TALKING-MACHINE.

Specification of Letters Patent.

Patented Sept. 22, 1908.

Application filed February 28, 1907. Serial No. 359,791. a I

To all'whom it may concern:

Be it knownthat I, HEINRIQHKLENK, a

subject of the Emperor of Germany, and resident of Hanau-on-the-Main,Germany, have invented a certain new and useful Im rovement in Talking Machinery, of which t e following is a specification. g

This invention relates to a talking machine and has for its the sound and enrichment of the tone in such instruments. To this end the casing is provided with a series of strings which are directly or indirectly caused to vibrate by the sound waves produced by the talking machine. They vibrate directl when arranged l; of the said machine and are therefore struck by the sound waves. It suflices however to attach the strings to the casing preferably by inter- I posing one or more resonance boards without aving the trum et open exactly behind the sound orifice. n this case the strings are caused to vibrate by the soundin trumpet setting the surrounding air and t e casing itself and attached resonanceboards into vibration, which'vibration is transmitted to the strings. With such an arrangement it suffices to provide groups of'strings so that each group corresponds to a definite tone, in order to strengthen the clear tones, for instance those of the iano and violin; whereb the reproduction o the tones is enriched. further increase of the fullness of sound and enrichment of the tone is effected by the ar-' rangement of attuned strings so thatfo'r each note 0 the talking machine at least one string i caused to vibrate: 'while' this takes place with the arrangement of suitable strings or of these. I

Preferably the invention is so devised that the casing forms at't-he same time the resonance board of an attuned stringed instrument, the efiect being further increased by ,interposing a sound post or voice between the trumfpet of the talking machineand the Besides the enrich bridge .0 the strings. ment of the tones in the reproduction of a ment or at least to play some accompanigroups of like strings or with some of.

y In the accompanying drawing which illustrates several embodiments of-the invention Figure 1 is a front elevation of a talkin machine inclosed in a casing, the strings eing stretched on the front wall of the casing provided with the sound orifice. Fig. 2 1s a longitudinal section of the construction shown in Fig. 1. Fig. 3 is a part longitudinal section showin a modification. Figs. 4 to 6 show two furt er modifications of a talking apparatus inclosed in a casing combined with a zither.

I As shown, the casing is formed like a box in the lower art of which the talking machine is fitte which consists in the .usual actuating mechanism 1, the rotatable record .disk 2,'the stylus 3, the sound box 4, and the movable arm 5. On the'arm 5 which is piv-, oted to the ball joint 6 is connected the t'rum et 7. The mouth of this latter is opposite t e sound orifice of a wall 8 serving as a resonance board, which forms only a part of ,the front wall of the casing. In front of it is provided another resonance board 8 which extends to the lowest quadrant of the sound orifice and is secured-to a rectangular frame 9. The u per bar of the frame carries the string-bloc '10 to which strings '11 are connected, which are led over the bridge 12 of the board-8 to the hooks 13. The board 8 is kept apart from the board 8 by a distance piece 14. The trumpet7 is connected in any manner, by small ties, or by an annular flange, with the board 8, .The front side of (the upper part of the casing has doors 15, 16.

The lower part of the casing in which is the rotatable record disk is accessible by a hinged door 17 so as to be able to exchange the records.

The sound waves produced by the apparatus and issuing from the trumpet pass throu h the mouth ofthe same into the air creased; and unpleasant accessory sounds produced in any case by the talking machine are rendered inaudible.

The connection of the trumpet 7 with th board 8 need not take place at the mouth of the former but may be eflected as shown in Fig. 3 by means of a sound post 19 secured to the neck of the trumpet. I

In the construction shown in Fig. 4 the disk 2 is rotatably arranged in known manner in the casing open at one end. The sound box 4 is operated'therefrom by means of the stylus, the sound box being connected to the movable arm 5 and the trumpet 7.

Above the upper wall 20 of the casing is arranged a second wall 20 which carries the string-block-lO, the bridge 12'and the hooks '13 for the strings 11. formed bythe walls 20 and 20 has the form The resonance board of a zither (Fig. 6).

The sound waves produced by means of the disk through the medium of the stylus and sound box pass for'the greatest part through the trum et into the air. A part however will simu taneously with the vibrations of the trumpet set the entire casing in purer.

vibration, the vibrations being transmitted to the upper resonance board and .so to the strings. At each note the correspondin string which is attuned thereto vibrates an strengthens the tone. If the trulmpet is as shown in Fig. 4 secured to the lower wall 20 the vibrations of the trumpet are better transmitted to the board. Further the strings can be struck to the tune reproduced by the talking apparatus or anaccompaniment or at least some primary accord can be played.

In the construction shown in Figs. 5 and 6 the sound waves act on the strings in the same manner as in the case of Fig. 4. Only, the action is further increased by interposing a sound post 19 between thetrumpet 7 and the bridge 12, which passes through a slot in the lower board. In this way a dlrect transmission of the vibrations of the trumpet to the strings is effected so that these are considerably assisted, that is the tone is louder and tral part of the casing is divided into three compartments in the middle one of which is the record disk, and in the outer one are the piano keys 21. The keys 21 are connected y the usual mechanism 22, which is only indicated diagrammatically, with the hammer 23. The strings 11 form part therefore of the strings of a iano.

In the repro uction of a tune by means of this apparatus by striking the keys 21 the melody can be accompanied or at least a vamp can be played or a mechanical accompaniment effected.

It is to be understood that by the term talking machines I mean to include gramophones, graphophones, phonographs and the 1 e.

Having described my invention what I claim and desire to secure by Letters Patent of the United States is 1. The herein described apparatus, comprising a casing, a talking machine inclosed therein and strings attached to said casing, said strings adapted to be vibrated by the sound waves produced by the talking machine.

2. The herein described apparatus, comprisin a casing, a talking machine inclosed 1n said casing and having a trumpet, and res onance strings arranged in front of the trumpet, the trumpet and the front wall of the casing serving as a resonance board.

3. The herein described apparatus, comprising a casing, a talking machine inclosed 1n the casing and having a trumpet, a double resonance board arranged in front of the trum et, of which board one member has a soun orifice opposite the mouth of the trumpet, and a bridge and strings and securing devices carried by the other member of the double resonance board.

4. The herein described apparatus, comprising, a casing, a talking machine inclosed 111 said casing, and strings attached to said casing, said strings being attuned to the talkin machine.

In testimony whereof I have signed my name to this specification in the presence of I two subscribing witnesses.
